MATLAB: Two figures in one GUI

gui

Hi. In my GUI i want to open new window with axes (clicking the button) and to plot trend on these axes. As Ii understand the onlyway to do it is to create new GUI with its own m-file.But new GUI has to use data from first(main) and i don't know how t0 do this. So the questions are: 1)How to open new (secodary) GUI from main GUI 2)How to use data from main GUI in secondary GUI

Thanks in advance.

No, that's not true. You don't need a second m-file. You can simply call figure() from whatever callback function you like (to create a brand new figure window), then plot(), subplot(), imshow(), or whatever and start drawing/displaying/graphing in it.

MATLAB: How to close one GUI figure window from another GUI using a uicontrol’s callback in MATLAB 7.8 (R2009a)

You can use FINDOBJ function to find the handle to the first GUI's figure window. Suppose the name of the first GUI is 'gui1' and the second GUI has a Push Button that should close gui1 when pushed. Insert the following code into the callback of a Push Button:

hf=findobj('Name','gui1');
close(hf)

MATLAB: How to call a callback within a callback from a different GUI

If you create the GUIs using GUIDE, then each will have its own handles structure. handles structures are attached to individual figures. In order for one gui to be able to access the handles of the other gui, it must know or be able to find the handle of at least one object in the other figure.

For example:

myfig = ancestor(hObject, 'figure');
allfig = findobj('type', 'figure');
otherfig = setdiff(allfig, myfig);
otherhandles = guidata(otherfig);
get(otherhandles.edit3, 'String')   %or whatever

If you know some unique property of the other figure, you can look for it specifically:

otherfig = findobj('type', 'figure', 'name', 'Frodo''s Guide To Third Breakfasts');

Now that you have the handles of the other GUI, you can fetch the callback properties:

item_handle = otherhandles.edit3;
cb = get(item_handle, 'Callback');

The way to invoke the callback after that depends upon whether it is a string or a file handle or cell array. If it is a handle or cell then it needs to be passed its own handle

fake_event = [];
if ischar(cb)
    evalin('base', cb);
elseif iscell(cb)
    cb{1}(item_handle, fake_event, cb{2:end});
elseif isa(cb, 'function_handle')
    cb(item_handle, fake_event);
else
   error('callback was wrong class, was %s', class(cb));
end

Notice that above I used fake_event = []. That will work for most callbacks, but some kinds of callbacks such as WindowKeyPressFcn need a structure of information giving details about what is happening. In order to successfully invoke such a callback, you need to create an appropriate struct and pass it in. For example http://www.mathworks.com/help/matlab/ref/figure-properties.html#property_windowkeypressfcn

fake_event = struct('Character', 'A', 'Modifier', 'shift', 'Key', 'a', 'Source', item_handle);   %describes a press of a capital A

... Yes, it is this messy! When you execute someone else's callback, you need to create all of the state that would normally be created automatically.

The alternative to this is to use a Java Robot, figure out where the appropriate button or object is on the screen, and have the robot fake the click or keypress on your behalf.

There is a better way, though. If you need the code of a callback to be triggered by a different routine, then put all of the details into a function and have both places call the same function:

   %one GUI
   function FrodosLunchGuide_edit3_Callback(hObject, event, handles)
     select_fifth_cheese(handles);
   end
   %the other GUI
   function FrodosBreakfastGuide_push5_Callback(hObject, event, handles)
     other_handles = guidata( findobj('Tag', 'FrodosLunchGuide_edit3') );
     select_fifth_cheese(other_handles);
   end
